NO, Wheeler Remanufacturing had a rash of the blocks with cast cranks that they drilled so they would work in a auto or stick application. They recalled almost 125 BB Mopar engines after they had several problems with oil leaking THRU the crank and out of the center of the crank where they drilled them to accept the long imput shaft of the manual transmission. This is not a rumor or hearsay, I lived thru one such experience with a 400 BB I installed in a Hillsborough County Sheriffs car back in 1976. I was unlucky enough to have gotten one of their recalled motors that slipped thru and was shipped to me. After puliing the oil pan, rear main and trans several times to try and locate the leak We called wheeler Engine and talked to a line tech that informed us that "oh you must have got one of the recalled engines" he then proceeded to tell us about the cast cranks that they drilled blah blah blah. He informed me of a quick fix, I cleaned the back of the crank real good with carb cleaner, filled it with JB, then I installed a flat expansion plug in the back where the pilot bushing would go and WALLA, it worked, no leak!
